Ua tsaug rau qhov koob hmoov ntawm" kev tshawb fawb thiab thev naus laus zis yog thawj lub zog tsim khoom", qhov kev pom no tseem muaj kev cuam tshuam tag nrho hauv kev lag luam textile. Kev tshawb fawb thiab kev loj hlob ntawm textile fibers nyob rau hauv ntau lub teb chaws tsis yog tsuas yog txwv rau decorations nyob rau hauv lub neej txhua hnub, tab sis kuj nyob rau hauv kev lag luam kev tshawb fawb thiab kev loj hlob thiab lwm yam. Koj yog tus rushing posture tshaj plaws. Tom ntej no, Xiaobu yuav coj mus tsev kom nkag siab, qhov txawv ntawm Kevlar thiab Dyneema yog dab tsi? Qhov zoo ntawm ob yog dab tsi?
Tam sim no, Kevlar fiber ntau yog ib qho khoom lag luam. Nws yog fiber ntau tsim los ntawm DuPont hauv xyoo 1970s, tseem hu ua aramid. Nws cov kev tshawb fawb thiab kev tsim kho tus nqi yog siab dua li cov fiber ntau zoo tib yam, thiab peb lub teb chaws tsis tau ua tiav cov thev naus laus zis ntawm kev tsim cov fiber ntau, yog li nws tus nqi yog me ntsis zoo tib yam hluavtaws fiber ntau, feem ntau nyob ib ncig ntawm 400 / kg. Dyneema yog ib qho fiber ntau ua los ntawm ultra-siab molecular hnyav polyethylene khoom. Nws yog cov khoom tsim los ntawm lub tuam txhab txawv teb chaws thiab nws cov nqi kuj yog siab heev.
Yog li qhov zoo ntawm ob qhov cuam tshuam qhov twg? Kevlar fiber ntau zoo li qhov ntsuas ntsuas, nws cov ntsuas ntau yam zoo dua li Qidalun. Nws cov nplaim-retardant zog yog superior thiab siv tau raws li cov khoom siv hluav taws xob; Nyob rau tib lub sijhawm, nws muaj hluav taws xob qis thiab nthuav tawm cov khoom zoo li qub; rau cov khoom lag luam, tiv thaiv cua thiab hnub ci, muaj zog acids thiab alkalis thiab lwm yam tshuaj reagents muaj ntau dua. Lub zog ntawm Dyneema fiber ntau yog siab dua li Kevlar fiber ntau, tab sis nws qhov zoo yog sib zog dua Kevlar, thiab nws cov kev puas tsuaj zoo dua. Qhov tseem ceeb tshaj plaws yog qhov dej tsis kam thiab dej tsis kam ntawm Dyneema fiber ntau dua li qub. Yog li ntawd, Dyneema fiber ntau muaj kev siv dav hauv kev lag luam lossis kev lag luam tshwj xeeb.
